KENNEDY SPACE CENTER, FLA. - Off-loading of the redesigned external fuel tank that will launch Space Shuttle Discovery on the next shuttle mission, STS-121, begins in the Launch Complex 39 turn basin. The Pegasus barge delivered the tank from the Michoud Assembly Facility in New Orleans to NASA's Kennedy Space Center. After off-loading, the tank will be moved into the Vehicle Assembly Building and lifted into a checkout cell for further work. The tank, designated ET-119, will fly with many major safety changes, including the removal of the protuberance air load ramps. A large piece of foam from a ramp came off during the last shuttle launch in July 2005. The ramps were removed to eliminate a potential source of damaging debris to the space shuttle. The next launch of Discovery is scheduled for May 2006.
